Example 3
This embodiment is an alternative embodiment of the present invention, and is used to describe the present application in detail and in addition to the specific examples:
the embodiment provides a service security verification mechanism and a method. The method comprises single network element setting command verification and network level function verification. The client checks the sink adapter and is only suitable for a single-point setting command. For the client verification of the network level function, the client is sunk to the server for verification.
The method of the embodiment comprises the following steps:
the method comprises the following steps: network element level function verification (network element level verification)
In the related technology, a plurality of single-point configuration check methods are deployed at a network management client, and the problem of the mode is not great in a normal single-point configuration scene, but in a north access or end-to-end management scene, the check rules of the client fail, so that a command is issued to equipment to report an error, the time consumption is long from the command issuing to the return failure, and the rollback failure is easily caused by excessive issuing of wrong information, so that a network management server has a large amount of redundant data. The usability and the service safety are not easy to guarantee.
For the above reasons, in order to make the various verification rules as reusable as possible, it is considered to sink the various verifications performed by the client to the adapter. After the verification sinks to the adapter, the basic verification logic does not need to be changed, but compared with the client verification, the user can be directly prompted, the adapter verification only can throw out the exception, and a corresponding error code needs to be applied, which is the difference between the two. The network element level check of the single point setting command is scattered in each adapter and client at present, is scattered and is not suitable for uniform control and maintenance, a network element level uniform check module can be considered to be abstracted, and the scattered check processing of the original client and the adapter is centralized in the module.
The position of the unified check module in the whole network management architecture flow can have two options.
1. Adding a check layer between the subnet manager and the adapter;
under the structure, the check module is an independent layer, each command code sent to the adapter passes through the layer, and the check module is divided into three sub-modules of decoding, checking and framing. However, this method needs to change the adapter frame, the adapter subnet manager does not directly distribute to the adapter object after receiving the command, but transmits to the network element unified check module first, and the input parameters need to include the network element name and the command message. After the verification is passed, the verification framework needs to distribute the command to the corresponding adapter object according to the network element name.
2. The unified check module appears in the form of adapter public process and is directly embedded into the configuration flow of the existing adapter command code.
In the mode, the platform adapter framework is not required to be changed, the network element level check module provides an adapter public process externally and is directly embedded into an adapter command code configuration file, the check rule used by the command is directly configured in the parameter of the process, and the adapter framework is slightly changed in the mode.
The second method comprises the following steps: network level function check (network level check)
In this scenario, if a single point modifies the basic data of a certain network element, a service using the IP address by other network elements in the network may fail, and there is a risk of service interruption.
For the above reasons, it is necessary to perform network-level verification on some key basic data and service setting type commands of a single point. Considering that the requirement of network level check will increase gradually, a network level unified check module is added in the network management architecture.
The unified checking module is positioned in the server and comprises a checking frame, a checking message decoding module and a checking rule processing module.
After receiving the message sent by the client, the check framework needs to decode the current command before implementing the check, and each check rule processing class only receives the input parameters of a fixed type, so that the reusability of each check rule can be improved as much as possible. The decoding work is taken charge of by the decoding module, a decoding interface can be abstracted, and the decoding interface is realized by each application to process the decoding work. The check framework may load the decode processing class via a configuration file.
And after decoding the original message, the decoding module processes the message into a data type which can be identified by the check rule and then returns the data type to the check framework.
After the check message decoding work is finished, the check frame distributes the data formed by decoding to each check processing class for formal check. In order to decouple all the check rules so that all the applications can realize all the check rules by themselves, the check framework provides a common check interface, and all the check rules realize the interface.
The calibration rules calibrate the parameters according to certain service logic, if the calibration is not passed, the calibration rules throw out exception, and the whole calibration process is interrupted; if the check passes, the checking framework passes responsibility to the next checking rule class.
The whole process is as follows:
1. and the decoding module is responsible for receiving the check message and calling the decoding module to decode according to the configuration file.
2. And after the decoding is finished, calling a verification rule corresponding to the command code to verify the message according to the configuration file.
3. After the verification is passed, the message is redirected to a final destination.
The network level checks employ concurrency control. Only the data is checked, and for illegal operation, the prompt is only needed to prompt that the operation is not allowed, and automatic association processing is not carried out. Therefore, the verification only relates to the checking of the network element data, does not relate to the modification of the network element data, and can consider the concurrent verification of multiple commands considering the cost performance of input and output, and the network-level verification framework does not perform special concurrent control on the concurrent verification and does not lock related network elements.
The check rule is different according to different processing mechanisms of external services of the access server, and comprises the following steps:
if the command is issued through the client, the original judgment standard is directly adopted, whether the issued command meets the standard or not is judged according to each functional command list on the client, if not, a failure result is returned, otherwise, a normal result is returned and issued to the equipment through the server;
if the north interface service process is accessed to the server, the interface list provided by the north service is used as a check standard to judge whether the issued command meets the standard interface list, if not, a failure result is returned, otherwise, a normal result is returned and issued to the equipment through the server;
if the access server is an end-to-end service process, the control command provided end-to-end is taken as a check standard to judge whether the issued command is attached to a standard command list, if not, a failure result is returned, and a normal result is returned and issued to the equipment through the server.
Fig. 3 is a flowchart of a service security check mechanism according to an embodiment of the present invention, and the service security check mechanism and method for a single network element include:
as described in the first method, if a single-point setting command, such as some parameters of a service configuration command, does not refer to basic data of other network elements and only affects the local network element, a network element level check module is used to centralize the dispersed check processing of the original client and adapter in the module. Under the structure, the checking module is an independent layer, all command codes sent to the adapter can pass through the layer, the checking rules are relatively centralized, and unified control and maintenance are utilized.
As described in the second method, the network-level check module is used for a single-point setting command, for example, some parameters of the service configuration class command refer to the basic data of other network elements. The network level check module adopts concurrency control, analyzes abnormal code streams after decomposition and processing of three sub-modules of the check frame, the decoding module and the check rule processing module, and reports the abnormal code streams to the client to throw the abnormal code streams for judgment of users. The processing mode has high processing speed and clear processing flow, and can accurately process the abnormal code stream, thereby greatly improving the safety of single-point service.
Fig. 4 is a flow chart of a service security verification mechanism provided in the embodiment of the present invention, which includes:
the method comprises the following steps: and issuing a verification command and receiving data.
Step two: the client judges whether the command is at the network element level. If the network element level is the network element level, a network element level checking method is started, and a checking result is returned.
Step three: the server determines if it is a network level command.
Step four: and judging whether the access is the access of a northbound interface.
Step five: if the command is accessed by the northbound interface, whether the command is correct is judged according to an interface check list provided by the northbound interface.
Step six: and judging whether the access is end-to-end access.
Step seven: if the access is end-to-end, whether the command is correct is judged according to the standard command specification provided by the end-to-end item.
Step eight: the verification is complete and the result is returned.
Step nine: and finishing the verification.
Through the network management service security verification mechanism and method provided by the embodiment, after a client receives a command, whether the command only affects the local network element is judged, if so, the command is issued to an adapter, and an illegal command or an abnormal command is processed by a network element level verification module of the adapter; if the command also affects other network elements, the command is issued to the server, and the network level check module located in the server processes the illegal command or exception.
The scheme of the embodiment not only reduces the risks of reducing the efficiency of the client and even abnormal exit caused by the fact that a large number of abnormal codes are concentrated in the client for processing, but also ensures the efficiency of processing commands by the client; the abnormal information processed is very accurate and efficient, the accuracy of the service safety check is improved, the practicability and the user experience of the function are improved through the service safety check of two levels of a network element level and a network level, the probability of engineering faults which are greatly influenced by service interruption and the like is greatly reduced, and the difficulty, the cost and the risk of maintaining the service by engineering maintenance personnel are reduced.
